Question

atoms in a single molecule of methane, ch4, share electrons. methane is formed by ____ bonds joining ____ atoms.

ionic; five
hydrogen; two
covalent; five
ionic; two

Explanation:

Covalent bonds involve sharing of electrons. In methane ($CH_4$), one carbon atom shares electrons with four hydrogen atoms, making a total of five atoms joined by covalent bonds. Ionic bonds involve transfer of electrons and hydrogen bonds are a type of intermolecular force, not the bond within a methane molecule.

Answer:

covalent; five
